Ring, a upper end of hanging are connected with the salvaging ring, and lower end is formed with the rotatable convolution for blocking turbogenerator upper end convex block
Slot, described hang are formed with a sliding slot on drum outer wall, the rotation preventing device can slide up and down in the sliding slot, two institutes
It states locating ring and is accordingly set with and is fixed in up and down and hang rotation preventing device to be limited in sliding slot on drum outer wall, on the rotation preventing device also
It is connected with the positioning pin, the upper and lower ends of the positioning pin are respectively equipped with a clamping block, on the inner wall of two locating rings
A card slot is accordingly formed with up and down respectively, wherein the clamping block being located above can be locked at the card for the locating ring being located above
To avoid rotation preventing device slide downward in slot, after rotation preventing device is by downward thrust, the clamping block disengaging being located above is corresponding
Card slot, rotation preventing device slide downward simultaneously make its lower end be inserted into convolution slot so that the convex block of turbogenerator upper end is locked in convolution
In slot, being fixedly connected for cylinder and turbogenerator is hung to realize, at the same underlying clamping block be locked at it is underlying fixed
To fix rotation preventing device in the card slot of position ring.
The rotation preventing device upper end is additionally provided with a plectrum convenient for pushing rotation preventing device to slide up and down.
The beneficial effects of the invention are as follows：Logging while drilling apparatus turbogenerator fishing tool provided by the invention is mounted on turbine
On generator, positioning pin, which plays rotation preventing device, to be locked, and is prevented fishing tool from falling off, can be risen in well head to turbogenerator
Crane operation has reached the function that turbogenerator is lifted by crane in well head, and fishing tool Assembling is convenient, has prodigious practical meaning
Justice.
Description of the drawings
Fig. 1 is the structural schematic diagram of logging while drilling apparatus turbogenerator fishing tool of the present invention；
Fig. 2 is the structural representation that logging while drilling apparatus turbogenerator fishing tool of the present invention is mounted on turbogenerator
Figure.
Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments：
Referring to Fig. 1 and Fig. 2, logging while drilling apparatus turbogenerator fishing tool of the invention includes hanging cylinder 1, rotation preventing device 2, two
A locating ring 3, positioning pin 4 and salvaging ring 5.
1 upper end of cylinder of hanging is connected with the salvaging ring 5, and lower end is formed with convolution slot 11.11 quantity of slot of circling round is two,
And two convolution 11 central symmetries of slot.Two convolution rotatable two convex blocks for blocking 6 upper end of turbogenerator of slot 11.
Described hang is formed with a sliding slot on 1 outer wall of cylinder, the rotation preventing device 2 can slide up and down to mounted on the sliding slot
Interior, 2 upper end of the rotation preventing device is equipped with a plectrum 21, in order to which operating personnel push rotation preventing device 2 to slide up and down manually.Described in two
About 3 locating ring is accordingly set with and is fixed in and hangs on 1 outer wall of cylinder so that rotation preventing device 2 to be limited in sliding slot.On the rotation preventing device 2
Also be connected with the positioning pin 4, the upper and lower ends of the positioning pin 4 are respectively equipped with a clamping block, two locating rings 3 it is interior
Accordingly it is formed with a card slot on wall up and down respectively.Wherein each locating ring 3 is fixed on by two screws described respectively
It hangs on cylinder 1, positioning pin 4 is fixed on by two screws on rotation preventing device 2.The rotation preventing device 2 passes through the locating ring 3, described fixed
Position pin 4 is fixed on described hang on cylinder 1.Each clamping block both sides on positioning pin 4 are each formed with groove, centre is formed with opening,
During clamping block is inserted into corresponding card slot, clamping block is first shunk to opening, when the groove of both sides enters corresponding card
